About This Data
The 2012 BMW 318i Sport Plus has an MOT pass rate of 81.8% based on 819 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 35,225 miles on the odometer. With a 18.2% failure rate, the 2012 318i Sport Plus is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 2012 BMW 318i Sport Plus, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to tyres: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating. With relatively low average mileage of 35,225 miles, many of these vehicles are still in good mechanical condition.
Tyres — 5.5% of failures
Tyres issues account for 5.5% of MOT failures on 2012 BMW 318i Sport Plus models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Brakes — 2.2% of failures
Brakes issues account for 2.2% of MOT failures on 2012 BMW 318i Sport Plus models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Exhaust, Fuel and Emissions — 1.7% of failures
Exhaust, Fuel and Emissions issues account for 1.7% of MOT failures on 2012 BMW 318i Sport Plus models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
